coatingaofsuitable material toconstitute aJdecorative surface of the desired appearance. This external coating is produced .in .the ,prefabri! cation.

Furthermore, the elements are constituted .in such manner that the component, once :the elements are fitted and fixed one on the other, presents cavities at its two extremities. Two adjacent cavities enclose a vertical space which can serve as a casing in which to'pour concrete cons stituting skeleton uprights or posts 'ofthe build ing. These acaxiities can Zthiis :serye Ior lthe fixing of the component parts or material on posts or standards previously mounted or placed in position afterwards. They also serve for attaching the walls by fitting into special .parts for the angles of the building.

The invention also comprises a building method by means of the prefabricated components which have just been described, which method is characterized by the assemblage of the elements and their fixing by means of keys and the later attachment of the parts thus assembled by pouring concrete into the lateral cavities.

The accompanying drawings show one method of carrying out the invention:

Figure 1 shows the component mounted and placed in position.

Figure 2 is an embodiment with the component in a portion of a wall with a corner of the building.

The component or material comprises two ele- 2 v. LI and Zthan theribs 15 of the element I, sothat "the elements .l and} fit one .into the other as shown.

The inclinations .of the .faces 1 and 4-! are approximately the .same .in .order to facilitate 'the fitting together .of the elements :1 and 2. Once fitted together, the ribs 9 come "inside the ribs .E/and .the elements .I and 2 are made integral by the keys .3.

The elements .I -.and 2 and also .the keys 3 are prefabricated. .They are preferably made of concrete and .in particular of vibrated concrete .in order to obtain -a resistance to compression .0: 300 leg/cm To give .at least one-of =these-elements an agreeable aspect, the: slabs' l and possibly the slab 8 are made .in-such manner as :to provide .an external facing :formed by a coating having the desired appearance. This coating can in particular be obtained by :meansof grains of quartzite crushed .to .a state of granulation suitably determined to .give the part the appearance of worked stone. In this 'way :all desired variations -.or aspects can be :obtained. For reasons of economy, the element I can be :made of concrete and the element 2 of clinkersconorete.

The "elements :I and .2 :as described, when once assembled by the :-keys 3,- ;permit the" construction of 1a .l-igh't and strong self-supporting wall capable-.of substituting :ior buildingsot-stone and replacing -.the-.latter :in districts in which stone is lacking. In this respect, it is advantageous to make the elements of centimetres by 40 centimetres with a thickness of about 4 centimetres, these dimensions combining the advantages of strength, lightness, ease in manipulation and convenience of assemblage.

In order to obtain greater rigidity of the whole, it is arranged to connect together in a convenient manner the component parts made according to the invention, this attachment easily taking place in the course of the assemblage.

To this end, there are provided on the elements I and 2 at their ends and in the course of their manufacture, tenons [2 on the element l in extension of the slab 4, and tenons l3 on the element 2 in extension of the slab 8. When these elements are placed side by side, the tenons l2 and I3 of the adjacent elements come into contact, leaving an inner space [4 between the tremities of the keys 3, thus making the building integral and constituting at the same time its skeleton or framework. These posts are cast as the assemblage proceeds and they are preferably vibrated. The size of the post depends upon the dimensions of the tenons l2 and I3 as also upon the distance apart of the elements I, 2 once assembled. It may be determined at any desired value by construction of the elements I; and 2 according to the strength to be obtained.

In a normal method of embodiment such as that indicated above, the space 14 is about 15 cm. x 15 cm.

To obtain the attachment of two walls thus constituted, at right angles, a special arrangement must be provided at the angles of the buildings thus constructed, which arrangement is intended to take the ends of the component parts and to fit together with them. Such an arrangement is shown by Figur 2. It consists of a special part l6 having two dressed faces I! and [8 at right angles. On its two other faces 19 and 20, recesses 2i and 22 are provided to accommodate the tenons 12 of the adjacent parts. Holes are made in the faces I9 and 20 which are intended to take the keys 3 for connection with the ribs 6 and 9 of the adjacent elements.

The element 16 may be a monobloc and extend over the whole height of the wall. But it can also consist of superposed elements in particular of the same height as the adjacent component parts. It is hollow, the interior space 23 serving as coffering for the direct pouring in of concrete imprisoning the keys 3, with reinforcements 24 if required. The angle piece then forms a framework post made integral with the two adjacent perpendicular walls.

When it is desired to form an end of a Wall without angle connection, an element such as 25 (Figure 1) can be used, this element being intended to fit on to the terminal tenons l2 and 13 of the component part. This part 25 leaves a space 26 between itself and the rib 5, which space is filled with cement or concrete by direct pouring.

We claim:

1. In a building structure, a plurality of abutting columns of exterior and interior prefabricated plates, formed of a cementitious material, each of said exterior and interior plates having vertical rib sections adjacent but spaced from the vertical edges of said plates, said vertical rib sections of said exterior plate cooperating with, but lying outside, said vertical rib sections of said interior plate, and said rib sections of the exterior and interior plates of one column of plates and said rib sections of the exterior and interior plates of an adjacent and abutting column of plates forming a cavity with the edge portions of said plates, tapered concrete pegs eX- tending through each of said cooperating rib sections, the larger ends of said pegs extending into said cavity, and a concrete pillar in said cavity bonded to said rib sections and edge portions of said plates and having the larger ends of said pegs embedded in said pillar and bonded thereto.

2. In a building structure, a plurality of abutting columns of exterior and interior prefabricated plates formed of a cementitious material,

each of said exterior and interior plates having vertical tapered rib sections adjacent but spaced from the vertical edges of said plates, said vertical rib sections of the exterior plates of each of said columns cooperating with but lying outside said vertical rib sections of the interior plates of each of said columns respectively, and said rib sections of the exterior and interior plates of one column and said rib sections of the exterior and interior plates of an adjacent column of plates forming a cavity with the abutting edge portions of said plates, tapered concrete pegs extending through each of said cooperating rib sections of each column of plates, the larger ends of said pegs extending into said cavity, and a reinforced concrete pillar in said cavity bonded to said rib sections and said edge portions of said plates and having the larger ends of said pegs embedded in said pillar and bonded thereto.
